Nix Sweeteners to Avoid Spreading Antibiotic Resistance Four widely used artificial sweeteners—saccharine, sucralose, aspartame and acesulfame potassium—promote the transfer of antibiotic resistance genes in both environmental and clinical settings, report researchers at the University of Queensland, Australia, in The ISME Journal. They found that these four nonnutritive sweeteners promote horizontal transfer of the genes between bacteria, furthering the spread of antibiotic-resistant genes in the intestine. The researchers say the findings provide insight into the spread of antimicrobial resistance and point to a potential risk associated with ingesting the artificial sweeteners.

Weighted blankets that provide a cozy, swaddled feeling have been big sellers during the trying days of the pandemic, and a new study verifies that they do provide mental health benefits. Researchers from Sweden’s Karolinska University tested 120 patients with depression, bipolar disorder, anxiety disorder or attention deficit hyperactivity disorder for four weeks. They found that a weighted blanked led to better sleep and reduced fatigue, depression and anxiety, and increased levels of daytime activity. Weighted blankets are comforters with tiny pellets or metal chains woven throughout so that weight is distributed across the body; researchers recommend using a blanket that is about 10 percent of a person’s body weight.

Improve Sleep with a Weighted Blanket
People that struggle to eat the often-recommended nine servings of fruit and vegetables each day can relax: The latest research from Harvard, based on 26 studies of 2 million people from 29 countries, found that two and three daily servings of fruit and vegetables, respectively, were linked to the most longevity. Compared to only two servings of produce per day, five servings lowered the risk of death overall by 13 percent, cardiovascular disease by 12 percent, cancer by 10 percent and respiratory disease by 35 percent. Green, leafy vegetables, including spinach, lettuce and kale, and fruit and vegetables rich in beta carotene and vitamin C, such as citrus fruits, berries and carrots, showed benefits.Starchy vegetables, like peas and corn, fruit juices and potatoes, did not appear to reduce the risk of death.
